Temperature Regulation in Turkey Vultures
Temperature regulation by six Turkey Vultures (Cathartes aura) was studied at ambient temperatures (T,) from 11 to 40°C in a metabolic chamber. Within this range body temperature varied little, averaging 39.7”C, and the ratio of CO, production to 0, consumption averaged 0.76. The thermal-neutral zone (TNZ) extended from 26 to 40°C. Below 26°C evaporative water loss and the heat-transfer coeffic...
متن کاملMovement ecology of migration in turkey vultures.
We develop individual-based movement ecology models (MEM) to explore turkey vulture (Cathartes aura) migration decisions at both hourly and daily scales. Vulture movements in 10 migration events were recorded with satellite-reporting GPS sensors, and flight behavior was observed visually, aided by on-the-ground VHF radio-tracking. We used the North American Regional Reanalysis dataset to obtain...
متن کاملFlight Feather Molt of Turkey Vultures
—We document the molt sequence of flight feathers in Turkey Vultures (Cathartes aura) based on studies of captive and wild birds, and examination of museum specimens. We found an unusual pattern of primary replacement, which appears to be a modified form of Staffelmauser, or stepwise wing molt. A Staffelmauser-like strategy for replacement of the secondaries is also described. These patterns of...
متن کاملExperimental lead poisoning in turkey vultures (Cathartes aura).
Lead-induced mortality appears to have been a major factor in the decline of the California condor (Gymnogyps californianus). We orally dosed turkey vultures (Cathartes aura) with BB-sized lead shot from January 1988 through July 1988 to determine physiologic response (delta-aminolevulinic acid dehydratase inhibition, erythrocyte protoporphyrin levels, anemia), diagnostic tissue lead concentrat...
متن کاملFine-scale assessment of home ranges and activity patterns for resident black vultures (Coragyps atratus) and turkey vultures (Cathartes aura)
Knowledge of black vulture (Coragyps atratus) and turkey vulture (Cathartes aura) spatial ecology is surprisingly limited despite their vital ecological roles. Fine-scale assessments of space use patterns and resource selection are particularly lacking, although development of tracking technologies has allowed data collection at finer temporal and spatial resolution. Objectives of this study we...
